Reduce your weekly food shop
Mimi Harrison started Beat the Budget at university, where she found herself barely subsisting on late-night chips. She’s since shared 400 budget recipes with 260,000 Instagram followers, for everything from caramelised shallot pasta to peanut butter chicken satay curry (now arranged on her website by dietary needs or meal type). She never spends more than £20 on her weekly shop. A Beat the Budget book is due out in June. Many recipes cost £1 a portion or less.
